Try this...put out several similar biners (including the Spirit) in front of you. Now, pick each one up one at a time and just get the feel of it. If you're anything like me, the Petzl Spirit will just feel ultra-natural and comfortable. The grippy ridges where your forefinger opens the gate are super-smooth. The gate opens smoothly and evenly, and it's really light. If you want the Cadillac of biners without the weight, pick up a few of these.
